SPRING-MOTOR.

To 'all/whom it may concern f Be it known that I, ARTIN a citizen of theUnited States,.residing atv Galesville, kin the `county of Trempealeauand State of Visconsin, have invented cer- -tain new `and usefulrr`Improvements in SpringfMotors; and 1I do hereby. declare .the followingto be a full, clear, andfexact description ofthe invention, S h as will.enable. others skilled inthe art o which itl appertains to makel and usethe same. l Thisinvention relates to spring motors, andthe primaryobject o f theinvention 1s to provide aspring motor which embodiesk a kplurality of shafts and vcoil springs carriedv thereby, which areconnected in such a manz-4 ner, th'at.one setr of the springs carriedlby yLone'ofthe shafts ywill bev re-wound, by the unwinding of variousother setsof springs.

vAnother object of this invention 1s to prof "vide a mechanism whichactsautomatically for .Setting ythe :re-winding mechanism on any Vone of thevarious shafts when the springs thereon become? unwbund.

Astill further object of this invention vis toi provide a vsuitablegoverning mechanism kv.forcontrolling :thespeed of rotation of the 30.'l -With` the foregoing .and

Fig.` 2 is an endv the spring motor which is substantially rec# tangularin shapeand has a plurality of` longitudinally extending cross barsgsecured thereto, and a plurality of laterally extending cross bars 3secured thereto adjacent its end. The frame lhas journal brackets 4secured to thefupper surface of its ends and the cross bars 3 in whicharel rotatably journaled shafts 4. The shafts 4 'are positionedintermediate of the longitudi-` nally extending cross bars 2 and theside rails. 'of vthe frame las lis clearly shown by reference to Fig.lof the drawings.

The shafts 4 have one end of coil springs 6 securedthereto asis clearlyshown in Fig.

The ends ofthe shafts 4 opposite to the ones which are rectangular inshape, have small friction wheels 9 mounted thereupon about which wheelsare disposed friction vbands 10. The friction bands 10 have one of theirends secured to suitable cross pieces 11, and the other ends, secured toa band or flexible member-12 whichextendsentirely coaction with aquadrant 9.0, for holding. vthe friction bands 1 0 in frictionalengagement with the peripheries of the friction wheels 9 for forming abrake to prevent rotation of the shaft 4. i

ting a cushioning spiral spring 70. The rod 68 extendstransverselyiacross the frame 1 and is vconnected rto abell crank arm71,

which armis in turn connected to a rod 72.

Therod 72 is secured to the lever 55 which Vis carried by the frame 1upon the side opposite to .the frame/i2, soas to operate the intoengagement ywith the clutch segments 45, when the former are movedoutwardly upon the shaft 4. f

In the operation of the improvedmotor heretofore described: the springs6 are initially wound by the rotation of the shafts 4 in any suitablemanner by applying ahandle or analogous device to the rectangular ends 8thereof, and afterthe springs have been. kwound, four of them areemployed for rewinding ythe fifth, in cases wherein five shafts V andfive separate springs are employed as is shown in the drawings.

During the unwinding ofthe spring, the

shafts, 4 will be rotated in one direction, which will feed the nuts 39outwardly along ythe shafts and cause them to engagethe collars 43, atapproximately the time when the springs are completely unwound. The nuts39 engaging thecollars y43 will uponk further rotation 0f the shaftsforce them outwardly causing the clutch segments 44 to move intoengagement with the clutch segments 45,

and consequently rotating the shafts 4 in aV reverse direction tofthevdirection of rotation during the unwinding of the spring, and cause thesame to rotate in a winding direction for the springs and wind them4about the shafts. When the frames 42 are moved outwardly by the nuts 39,the rods 58 are operated for causingthe levers 55 to move into fengagement with the, ratchets 54 and prevent the unwindin of the springsduring therotation thereof:

The springs are wound and the shaft rotated in a winding direction ofthe springs by theshafts 25 and 47, which shafts are in turn rotated bycertain of the shafts 4 K through theinterme'shing engagement of theworms 21 and the worm gears y26 carried by l `ing the clutch segment 44out of engagement with'` the clutch segment 45, and releasing the'ratchet wheels 54 from engagement by the levers 55, which leaves theshafts 4 which has been recently rotated in the winding direction freefor unwinding rotation of the springs. The winding shaft 47 is gearedfor rotation at an increased. rate 'of speed so that the winding of thesprings may be accomplished in a muchless lengthl of time than isnecessary for the unwinding thereof.

From the foregoing description taken in connection with the accompanyingdrawings the advantages of construction and of the method of operationof the improved spring 7 motor. will. .be readily apparent to'lthoseskilled in the art to which this invention appertains and, while in theforegoingedescription, the principle of the operation of thisinventionhas been` described together with various features of construction, itis to be understood that certain minor features `of ditions providedsuch alterations are 'comprehended within the scope l of what isclaimed.
